The present invention relates to a web-based management apparatus and method, and more particularly, to network device management using an extended generation language.

Management of the network and the network device has been proposed in various ways according to the development of the technology. Traditionally used methods have a management method with a central server using a network management protocol such as Simple Network Management Protocol (SNMP) or Transaction Language 1 (TL1), and the SNMP-based management method is managed by one administrator. Collect information through periodic information exchange with agents.

1 illustrates a conventional network management scheme.

Referring to FIG. 1, in the centralized management method using SNMP, all management functions are concentrated in one management system (NMS) 140, and the several management agents 110, 120, and 130 are simply It only performs the function of collecting data.

The management agents 110, 120, and 130 may perform only fixed functions, and when an emergency occurs in the network, the agent may not solve the emergency by itself and manage for quality of service (QoS) of the multimedia service. There is a problem with the lack of functionality.

Although the network management method as described above has a small number of agents to manage or use in a small network such as a local area network (LAN), the management system 140 is difficult to manage a large entire network. However, in a large network, there is a problem in that management traffic increases and a lot of time is spent processing the management information.

In addition, as the size of the network grows, automatic network management is required, and management needs for services provided are also increasing.

However, in order to manage the network device, there is a problem in that a management interface for supporting each command is generated for each device after defining a management item of the device, generating and defining a corresponding command. .
